Key clinical point: Signatures of circulating microRNA in patients with psoriatic arthritis (PsA) and patients with psoriasis were significantly different from those in control individuals, with some even being differentially regulated between PsA and psoriasis.
Major finding: Overall, 9 microRNA best differentiated patients with PsA and psoriasis from control individuals (area under the curve [AUC] ≥0.70; all P < .05) and 4 microRNA best differentiated patients with PsA from patients with psoriasis (all P < .05). A combination of 4 microRNA (miR-19b-3p, miR-21-5p, miR-92a-3p, and let-7b-5p) vs miR-92a-3p alone could better differentiate between patients with PsA and psoriasis (AUC 0.92 vs 0.82).
Study details: This cross-sectional study included 51 patients with PsA, 40 patients with psoriasis, and 50 control individuals.
Disclosures: This study did not receive any specific funding. Two authors declared being employees or shareholders of TAmiRNA GmbH or holding intellectual property for the diagnostic use of microRNA in bone diseases.
